I drift forever with the current down these long canals they've made, Tame, yet wild, I run elusive Multitasking to your aid. Before I came, the world was darker, colder, sometimes, rougher, true But though I might make living easy, I'm good at killing people too.

Why this works

This riddle cleverly describes electricity through various metaphors and characteristics. The first line, "I drift forever with the current," plays on the dual meaning of "current"—referring both to the flow of water in canals and the flow of electric current. The phrases "tame, yet wild" and "elusive multitasking" highlight electricity's ability to be controlled for beneficial uses, like powering homes and devices, while also being dangerous if mishandled. The final lines contrast electricity's role in improving our lives (making living easier) with its potential for harm, as it can lead to accidents or fatalities if safety precautions are not followed. Thus, the riddle encapsulates both the utility and the peril of electricity in our daily lives.
